Set Free by Language: Revisiting Humboldt’s Distinction between Linguistic Structure and Conceptualisation

Imagine holding a cup. It does not decide what one pours into it (tea, coffee, or water), but it sets the form and limits of the contents, how it is contained, handled, and offered. Wilhelm von Humboldt, a 19^th-century linguist, saw language similarly: a structure that he referred to as Weltansicht that modulates how we conceptualise the world. What we pour into that structure (our ideas, beliefs, emotions) he called Weltanschauung. The cup stays the same; the contents vary from person to person.

Humboldt (1767–1835) was a Prussian linguist, philosopher, and statesman. He believed that language was inseparable from individual identity and was central to how culture emerges. His travels exposed him to many languages and provided an insight into how linguistic structure might influence the way people perceive and understand the world.

Jürgen Trabant (born 1942) is a German professor of French and Italian linguistics who became one of Humboldt’s most attentive interpreters. Writing in the early 2000s, and most notably in work consolidated by 2009, Trabant sought to recover nuances in Humboldt’s work that had been flattened by later scholarship. To grasp Trabant’s distinctions, it helps to consider the modern idea of affordances. In language, affordances are built-in possibilities (patterns of grammar, meaning, and expression) that make some expressions feel more natural than others. For example, in English we frequently use modal verbs like can to express ability, permission, or possibility: can see, can have, can fail. This makes it easy to express ideas of agency in nuanced ways. Other languages without a direct equivalent might express these concepts differently.

Trabant sought to recover a distinction between Weltansicht and Weltanschauung that had been flattened in English by the single word ‘worldview’. Humboldt had asserted that, like the fluid in a cup, the structure precedes the creation of conceptions and ideologies (without the cup one would pour fluid into nothing). Weltansicht operates at a ‘fundamental level’, in the first contact a human mind establishes with reality (through the senses). Affordances belong to Weltansicht; they are the implicit pathways a language opens up before any worldview is formed. Only afterwards do ideation and interpretation take form, leading to Weltanschauung.¹ Trabant showed that Weltanschauung relates to worldview as ‘visions of the world in the sense of conceptions and ideologies’².

In the 1930s, American linguists Edward Sapir and Benjamin Lee Whorf, expanding on Humboldt’s ideas, had developed what became known as the Sapir-Whorf Hypothesis. Whorf in particular proposed that the structure of a language sets limits on what its speakers can think — a bold claim known as the strong version of the hypothesis. According to this view, speakers are confined to the concepts their language can express and thus experience reality in fundamentally different ways. The idea was provocative, not least because it implied that language could trap speakers within narrow conceptual worlds.

In response, others proposed a weaker version — language not as a cage, but as a lens. To see how speakers circumvent the constraints of language, consider this exchange between two native English speakers:

Speaker A: I hate romance movies. They give us false hope — they all belong to the fakeness genre.
Speaker B: Fakeness genre?
Speaker A: Yes. They’re fake — romance movies show things that don’t work in real life. They break people’s hearts. Same with horror: apparently serial killers can magically disappear. They belong in the fakeness genre too.
Speaker B: How about sci-fi movies?
Speaker A: No, sci-fi is more sensical — even Back to the Future

Speaker A’s use of the phrase fakeness genre shows how language lets speakers invent categories that express personal judgment and experience. The phrase is not standard, but it is immediately clear.

The speaker draws on affordances in the English language, its ease with compounds and its habit of turning qualities into nouns. Fakeness does both: it turns an adjective (fake) into a noun with the suffix -ness, creating something that can be treated like a category. In that moment, the speaker is not merely inventing a phrase — they are constructing a judgment through the resources of language, a worldview on certain genres of film. Language provides the scaffolding by offering the tools and structure that make expression possible; experience, emotion, and judgment fill it out. Even speakers of the same language use these affordances differently, building meanings influenced by culture, memory, and individual values.

A worldview, therefore, does not emerge fully formed from a language, nor is it dictated by grammar or vocabulary. It emerges through the interplay between what a language makes possible and the lived experience that gives those possibilities meaning. A particular language’s affordances may make some ways of noticing or describing the world feel more natural, but they do not prescribe what is conceptualised.

Today, few people speak or think entirely within the bounds of a single language. People borrow, switch registers, and reach for words that feel more precise (or more resonant) in another language. English, in particular, often functions as a global lingua franca, offering tonal shortcuts to others. When a French speaker says le weekend, it is not because French lacks a word for it (fin de semaine exists), but because the English phrase conveys a particular tone: casual, modern, slightly informal. In choosing it, the speaker is not limited by the structures of French but is actively reaching beyond those structures to express a meaning that feels more resonant. We would not observe this behaviour if language did indeed dictate thought. It reveals instead that sometimes speakers draw on affordances to express a worldview that no single language fully contains.

If languages give us frameworks, they also allow us to depart from them. In that sense, our ways of seeing are not determined by language, but modulated through it. The cup defines a contour, but it does not dictate what is poured into it.
